New rumors suggest that Apple is currently testing prototypes of the iPhone 19 Pro and iPhone 19 Pro Max featuring quad-curved displays, potentially signaling a major design shift for the company’s future flagship lineup.

According to well-known Chinese tipster Digital Chat Station on Weibo, Apple’s 2027 Pro-series iPhones are being evaluated with curved panels that bend on all four sides. If the rumor proves accurate, it would mark one of the most dramatic display design changes for the iPhone in years.

The report is particularly interesting given the smartphone industry’s recent design trends. Quad-curved displays were once heavily popular among Chinese Android manufacturers before many brands eventually transitioned back to flatter panels inspired by Apple’s own design direction. If Apple adopts quad-curved screens in 2027, the move could potentially influence Android manufacturers to revisit curved-edge designs once again.

The rumored timeline also aligns with a significant milestone for Apple. The year 2027 will mark the 20th anniversary of the original iPhone, which was first announced in January 2007 before going on sale later that year.

Because of the anniversary, speculation has already begun regarding Apple’s future branding strategy. While the devices are currently being referred to as the iPhone 19 Pro and iPhone 19 Pro Max, Apple could ultimately choose a completely different naming scheme to commemorate the occasion.

At this stage, the information remains based entirely on prototype testing and early leaks, meaning Apple’s final plans could still change before the devices officially reach the market.
